New York Jets interception-machine Mark Sanchez might actually have done something right this year ... and her name's Kate Upton -- this according to the super model herself.

Rumors have been spreading like wildfire ... Mark and Kate are an item -- but we asked the buxom Victoria's Secret angel straight up ... are you single ... and she played coy, replying, "What do you think?"

We pressed a little more ... asking if Mark was the mystery man -- Kate hedged, responding, "I don't know!"

As for the real truth -- Kate tells us, "It's whatever you think!"

So here's what we think -- if Mark had any game, he would have AT LEAST made the playoffs.
